The accelerator housing machining method according to claim 6, characterized in that: the swinging direction and angle of the ball cage cutter are 76 degrees from the vertical state to the left, the swinging direction and angle of the end face cutter are 61 degrees from the vertical state to the right, and when the ball cage cutter swings to the maximum angle at the left side, the cutter (205) and the cutter seat front body (201) can extend into or out of the differential mechanism, and when the end face cutter swings to the maximum angle at the right side, the cutter (205) and the cutter seat front body (201) can extend into or out of the differential mechanism.
